W'INDOW VEN'AI'ILATOR Filed April 14, 1930 Patented Nov. 24, 1931 mms-"mm EONARD D. VGREEN, OF ERIE, PENNSYLVANIAV w'mnow VENTILATOR Application filed April 14,

This nvention relates to new and useful improvements in ventilators for windows and has for the primary object;` the provsion of a device of the above stated character which 5 may be applied to or form part of a window sash either constructed from wood or metal or of the sliding or swinging types and which will permit a personto easily and quickly ventilate a room without a direct draft.

Another object of this invention is the provision of means whereby the ventilatcr may be opened and closed as' desired to control the amount of air to the room according to the desires of the user.

A further object of this invention is the provision of means to prevent direct draft or flow of air through the ventilator when the air control means is partly or fully open.

A further object of this invention is the provision of an ornamental screen to be placed inside of the ventilator to prevent the entrance of foreign matter along with the air and which will produce a pleasing appearance to the device from any point within the room.

A still further object of this invention is the provision of a ventilator of the above stated character which will be simple, durable and efi'icient, and which may be manufactured and sold at a comparatively low cost.

lVith these and other objects in View as will become more apparent as the description proceeds, the invention consists in certain novel features of Construction combination and ar- 5 rangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention reference is had to the following description and accompanying drawings, in which:

Figure 1 is a fragmentary front elevation illustratng a window with a ventilator applied thereto and constructed in accordance with my invention.

Figure 2 is a fragmentary transverse sec: tional view. illustrating the ventlator and showing in dotted lines the air control in an open position.

Figure 3 is a fragmentaryfront elevation the casing `1.- The lower edge of-theplate 1 1930. serial No. 444227.-

in'a window sash 2 as clearly shown in Fg- 0 ures 1 and 2 of the oflicial drawingsj,` The sash`2'may be of any well kno'wnjtype' and' constructed from` any' material i now employed jin the making' of such' and is pro*- vided with an elongated openingto receive 0 thecasing l by cutting away the-glass`3 and strips 4 so that the'gla'ss and strips rest upon the'top wall 5 of the casing 1 as clearly shown in F igure 2.' The end'walls 'of the` casing are angularly bent and secur'ed to the window 9 sash 2 as shown at 6. A skeleton frame ;7 overlying the inner side wallof the casingis Secured' to the sash@ as shown wat 8. .The frame 7, is provided with a .pluralit-y ofielongated slots and may be of anyornamental design to 'provide an 'attractive appearance to the' device from a pointw'thin the room. An auxiliary frame carrying wire mesh- 9 -is positioned in rear of the frame 7 to closeth'e ;elongated slots and is securedtherein by clips 9 10 and 11 engaging portions ofthe inneriside i .wall ofthe casing. Theclips 10'and.1 l -;are; so arranged that the auxiliaryframe carrying the screen 9 may i be moi 'ed ,upwardly to disengage the clip 11 from thej'casing; 1 and &5 swung outwardly sufliciently to permitthe clip 10 to be disengaged from the casing'there'- by 'permittihgthe screen 'to b'e cleaned of foreign matter which may have adhered thereto. ;29

Thetop wall of the 'casing 5 is off-'set downwardly to form a seat for the glass 3 'as clear ly shown in Figure 3. The ou't'er side wall of the casingl adj acentthe upper edge' thereof is bent inwardly and upwardly to form a, flange 12 toreceive a correspondingly shaped -flange13 formed on the upper edge of aventi lation control plate 14 thereby establishing i ahinge 'connection between said plate 14 and 14 has a spring catch 15 formedthereon to engage over a bead 16 formed on the casing 1 when the plat e 14 is in a` closed position to prevent accidental swnging of the plate due to the 'wind striking against' the plate. The bead 16 forms a seat to receive a portion of the lower rail of the sash 2 as shown in Figure 2 thereby aiding in retaining t he casing 1 in position. v

An Operating lever 17 is secured to the inner face of the plate'l l and extends through a slot 187 in the frame 7 and is provided at its free end with a suitable finger grip 19. A lug 20 is carried by the level' 17 to engage in any one of a plurality of notohes 21 formed in the plate 7 for holding the plate 14 in various adjusted positions. y t

A' wind-deflector is ;positioned within the casing 1 and comprises 'a plate 22 Secured to the topand bottom walls of the casng 1 and is provided' with a plurality of struok-out 'portions 23rthat incline upwardly and outwardly from theplate 22 to provide wind defiecting elements which will prevent the air -from passing directly throughthe casing `1 with too great a Volume.

'in operation, when desirng to vent'ilate a room'w thout the necessity of opening the wardly swinging the `control plate 14: outone of said notches to hold the air control plate in various adjusted positions.

2. .A ventilator 'co'mprsing a casing including top, bottom and end walls, a screened 'plate closing one side of the casng, saidtop opening and closing the closure, said bottom wall .having one edge bent to provide a head,

and said closure grooved to receive the bead when in a closed position.

In testimony whereof I afiix my signature.

"window sash2, the lever 17 is moved downwardly consequently permitting air to pass v through the casingi .into the room in the amount 'desired The air passing .through the casng is deflected upwardly by the portions 23 of the plate 22 and prevents a direct draft 'into the room.

Re'ferring to my modified form of invention, the casing 1 may have the top wall 24 formed as shown in Figure 5, to engage a wooden -'strip 25 which is the lower porti-on of a wooden window sash, it being understod that the lower portion of the window sash is cut to form a slot to receive' the cas- While have shown and 'described the struction lcombination and arrangement of parte may be made without departing from the spirit and scope of the invention as I laimed'. v
